EAR FOR SHEET-METAL VESSELS.

SPECIFICATION forming part of Letters Patent No. 503,680, dated August22, 1893.

Application filed February 10, 1891. Renewed January 23, 1893. SerialNo. 459,445. (N 0 model.)

To all whom it may concern.-

Be it known that I, HENRY S. REYNOLDS, a citizen of the United States,and a resident of Brooklyn, in the county of Kings and State of NewYork,have invented certain new and useful Improvements in Ears forSheet-Metal Vessels, of which the following is a specification.

This invention relates to certain improvements in cars for sheet metalvessels, and is especially designed for that class of goods known asenameled ware.

I-Ieretofore in the construction of these goods it has been necessary torivet the plate carrying the ear to the vessel body prior to theenameling process, since its attachment subsequent thereto would breakand injure the enamel, and destroy the appearance of the vessel. Theseear attachments have usually been composed of malleable castings andconsequently of heavier metal than that of the sheet metal body of thevessel. Hence in enameling operations the difference in the characterand thickness of the metal of the ear attachment as compared with thevessel body has been a disadvantage, resulting usually in a failure toobtain a good finish to the article at the point of the ear attachment;this has been due to the thickening of the coating at the edges of theplate carrying the ear, and also because it is not possible to coat themalleable casting as evenly and smoothly as the sheet metal body.

It is the object of my invention to obviate these disadvantages andproduce an ear which will be neat and attractive in appearance, andwhich may be readily attached to the vessel subsequent to the enamelingoperation, and without injury to the enamel coating.

To this end myinvention consists of a projection on the vessel body, andan ear provided with a shouldered slot within which the said projectionis wedged, as hereinafter more fully described and claimed.

In the accompanying drawings, in the several figures of which like partsare similarly designated, Figure 1, is a fragmentary View of a vesselshowing the projection I prefer to employ. Fig.2, is a rear elevation ofthe ear, showing the recesses. Fig. 3, is a vertical section of earattached to the vessel. Fig. 4,

is a horizontal section on the line 00-00, Fig. 3. Fig. 5, is a sectionon the line yy, Fig. 2; and Fig. 6, is a side elevation of theprojection on the vessel body.

A represents the body of the vessel, to which the V-shaped projection 13is secured, as by a rivet a, prior to the enameling process. Thisprojection may be of malleable iron or other suitable material, and isof the form illustrated. The ear may also be of malleable iron or othersuitable material, and consists of the recessed base b, and ring-shapedextension 0, for the reception of the swinging handle of the vessel. Thebase is formed with a shouldered slot 1), in this instance a slot of theT or keyhole kind, the shoulders of the slot being beveledlongitudinally on that face which is engaged by the projection B, so asto be thinnest at the point where the projection first enters, andthence gradually increasing in thickness, as indicated in Fig. 5, at b.The faces of the projection B which meet these longitudinally beveledshoulders, are correspondingly inclined,as seen in Fig. 6, at 19 Theresult of this construction is that when the base is pushed-up intoengagement with the projection, it will also be drawn tightly againstthe vessel body, so as to make a close accurately fitting jointtherewith; this operation however, taking place gradually and in suchmanner as not to injure the glazed surface of the vessel. This featureis applicable not only to the particular form of base underconsideration, but to any base or handle plate which is to be attachedto a sheet metal vessel. The recess within the base may also belongitudinally tapered, as indicated by dotted lines in Fig. 2.

The operation is as follows: After the attachment of the projection tothe vessel, and subsequent to the enameling process, the upper andlarger part of the T-slot is placed over the projection on the vessel,as shown by dotted lines, Fig. 3, and the ear is then moved upwardly tothe position shown by full lines in Fig. 3, said car being guided by thevertical portion of the T-slot over the V- shaped projection, which, asthe ear is pushed upwardly is confined within the tapering recess andfirmly wedged therein, and at the same time acts to draw and hold theear most tightly and closely against the body of the the enlargedopening toward the bottom of vessel, forming a secure and strongjointure; and to render the same more stable, I introduce molten metalthrough a suitable aperture, such as cl, in the base of the ear, fillingthe cavity in the ear surrounding the projection on the vessel body andthus holding the ear firmly in its wedged position on the projection. Itwill be seen that an ear of this construction is neat and attractive inappearance, and will add to, rather than detract from the generalappearance of the vessel. 'It can also be cheaply made and readilyapplied, and if desired, may be nickel-plated, orotherwise ornamented.

What I claim as new, and desire to secure 'by Letters Patent, is

1. An ear for sheet metal vessels, comprising a base having a T-slottherein, the shoulders of the slot being beveled longitudinally, andgradually increasing in thickness from the slot, substantially as shownand described.

2. A base having a shouldered slot to engage a head or flangedprojection on the vessel body, the shoulders of the slot being beveledlongitudinally on that face which is engaged by the projection so as tobe thinnest at the point where the projection firstenters and thencegradually increasing in thickness, in combination with the vessel bodyand a flanged projection thereon beveled correspondingly to the beveledshoulders of the slot, substantially as described.

Signed at New York, in the county of New York and State of New York,this 2d day of February, A. D. 1891.
